6.3. EMBEDDING / SETTING THE DAMPER
NOTE
Ensure that at each place of the damper circumference there is a 2.5 mm gap between the body
and the partition. Fulfilling this comment is a condition of keeping the product warranty.
Securing the gap size between the damper body and the partition.
Protecting the damper against buckling.
Correctness of the mcr FID S/... c/P damper is maintained when the partition rotation axis is horizontal. The release
and control mechanism may be located on the right or on the left hand side of the damper at any direction of air flow.
Installation of the damper in such a way that the partition rotation axes are vertical is allowed only after prior
notification of the Manufacturer at the device order.
Before embedding/setting, place the damper axially in the partition (wall or ceiling which separates fire zones) in the
previously prepared hole. Then, level out and secure the device. After these actions, manually start the damper
partition, checking whether it rotates correctly (does not collide with the enclosure elements etc.). Close the damper
partition. Carefully fill the gap between the damper casing and the wall with the right mortar that ensures wall and
damper fire resistance, taking particular attention so that it does not get on the acting elements (release and control
mechanism, partition, gaskets, limits). To ensure it, it is mandatory to secure the damper with film, or any other cover
until the masonry and finishing works are concluded. The damper must remain closed until the mortar binds. After
the mortar binds, remove supports, open and close the damper in order to check the correctness of its operation. In
the case of installing the damper in a wall made of panels, tightly fill the space between the damper enclosure and
the wall with mineral wool with A1 fire protection rating confirmed by a certificate, as well as density and thickness
that ensures fire resistance no less than the fire resistance of the wall in which the damper is installed. The filled
space should additionally be sealed with a relevant mortar or putty that has the fire resistance required for the wall.
In order to ensure the fire resistance of the fire separation element, it is mandatory to observe the border of
embedding - the damper rotation axis must not be outside the wall.
